sessionid

问题 In the PHP 5.5.1, there's a reference to a SessionIdInterface. However, it's still undocumented and only thing I could find was the interface definition: interface SessionIdInterface { public function create_sid (); } Is it safe to rely on this interface? Where can I find some sort of documentation regarding this interface? 回答1: SessionIdInterface was created as part of php-src pull request 109 and landed in PHP 5.5.1. Some details on it are discussed there. In short, your

问题 I have a website that needs to perform a certain backend function once per user session. I therefore want to be able to determine whether any given page view is the first within a given session. According to the PHP docs: session_start() creates a session or resumes the current one based on a session identifier passed via a GET or POST request, or passed via a cookie. So is there any way to know whether the session is being created or resumed? Or is this a situation where I have to check the

问题 I have a standard html page that has a few img tags, each of these are pointing to a php file on our server. When the php file is loaded, it saves some data to the session before then generating an image. This data in the session from each of the scripts is then used in other script further in our application. The php file to generate the image starts with session_start and when using the native PHP session handler all seems to work great. Each execution is done correctly and the full session

问题 I have grails application, using sessionRegistry I can get sessionId. Now, how can I get HttpSession from that sessionId. 回答1: If you want the HttpSession then how about this: import org.springframework.beans.BeansException import org.springframework.context.ApplicationContext import org.springframework.context.ApplicationContextAware import org.springframework.stereotype.Component import org.springframework.web.context.WebApplicationContext import javax.servlet.http.HttpSession import javax

问题 I want to be able to get the SessionID of the currently authenticated session in a WebMethod function where EnableSession = false . I cannot set EnableSession=true on this request, because another (long running) request on a different page is keeping the SessionState locked (EnableSessionState == "True" not "Readonly"). Is there a consistent way of getting the SessionID from either the ASP.NET Session cookie or the Url for cookieless sessions? I can code it myself but I would rather use a

问题 This web page http://www.w3schools.com/ASP/prop_sessionid.asp states that a session ID is generated on the ServerSide. If this is the case, then how does a server know it's still the same client on the 2nd request response cycle? Surely the SessionId would be generated on the ClientSide so that the client would be sure of passing the same value to the server? 回答1: The SessionID is generated Server Side, but is stored on the Client within a Cookie. Then everytime the client makes a request to

问题 On our websites we want to make it possible to share sessions accros multiple domains. All these websites are on the same server but some of them have a different IP address. The possible solution I found was to set the session ID myself: <?php session_id($someUniqueHash); ?> And this works, if I make the hash like md5('test'). On a other domain on te same server we have the session again. The problem is generating the ID. I see some solutions on the internet with microtime etc, but when I

问题 One of my sites is for old mobile phones that don't accept cookies so it uses a URL-based Session ID. However, Google is indexing the Session ID, so when my site is searched on Google, all the results come up with a specific Session ID. On most occasions, that Session ID is no longer valid by the time a guest clicks on it, but I've had at least one case where a guest clicked on a link from Google and it actually logged them into someone else's account, which is obviously a huge security flaw.

问题 I'm trying to understand better how Windows sessions work, so if I have some weird mistakes in the question, please, let me know. I use LsaEnumerateLogonSessions() to get all the logged on sessions in the system. Now I have LUID that represents a log-on, and if I understand correctly, it represents a user that logged on or a build it user like SYSTEM. Now, if user X starts a process, Windows gives that process a token that represents X. Is there a way (in a Windows service) to get the user's

问题 We are creating a web site with ASP.Net Framework 4.5. I know the way to generate a new sessionId using SessionManager for the current httpContext. I also believe that the sessionId field is readonly and cannot be modified. However, is it possible to create a new session having a sessionId of my choice? For example, if I want the current session Id to have a value "ASDFGHIJKLQWERTY", is it possible to create one? The client insists that it can be done. However, I strongly believe that this is
